Problems solved by technology

[0002] Automobile dustproof boots (sealing bowls), shock absorbers, etc. used in the automobile industry are generally made of rubber materials. Due to the performance of the rubber itself, it is determined that it is a vulnerable part, but it is very troublesome to replace the dustproof boot. Timely replacement will wear out the steering mechanism of the car and affect its life
Due to the large difference between the shape of the dust cover, the product is not easy to release the mold during the demoulding process, and sometimes the dust cover is elongated and broken, which affects the quality of the product. When it is installed on a car, the service life is shortened and it is easy Cracks, which affect its life, bring troubles to users in car maintenance and wear and tear on steering mechanisms

Embodiment Construction

[0004] In order to better understand and implement, specific examples are given below in detail: a manufacturing process of automobile dustproof equipment according to the present invention. Select the polyurethane elastomer material to carry out the raw material drying, mold heating, and injection molding process steps according to the conventional process. After the injection molding process is completed, after cooling for 120 seconds, enter the demoulding process step. First, the injection machine performs the mold opening action. At this time, in Under the pulling action of the movable template, the mold is in the mold-opening state; after the mold is fully opened, the 10 MPa compressed air in the air pump is inflated into the end of the die head through the air-filling channel and enters the dust-proof jacket, and the dust-proof jacket is in the air After the dust jacket is fully inflated, the hydraulic ejector mechanism of the injection machine starts to move and ejects f...

Abstract

The invention discloses a manufacturing process for automobile dustproof equipment. The manufacturing process comprises the process steps of raw material drying, die heating, injection moulding and die release. The manufacturing process is characterized in that compressed air is charged in a dustproof sleeve by an air pump through an air charging channel in the process step of die release, thus the die release is facilitated. Therefore, the die release is easy, the dustproof sleeve is free from the phenomena of stretching and breakage, the product quality is improved, the service life is prolonged, the replacement times is greatly reduced, and an automobile steering mechanism is protected from wear while the cost is saved.
